COMBINED CHURN AND BUTTER-WORKER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed November 17, 1906. Serial No. 343,926.

To all whom, it nuty concern:

Be it known that we, OL CHRISTENSEN, of Vesterbrogade, No. 30, Copenhagen, in the Kingdom of Denmark, dairy expert, and CHRISTIAN PETER SoLBEcK, of Istedgade 45, Copenhagen, in the Kingdom of Denmark, merchant, have ointly invented new and useful Improvements in a Combined Churn and Butter-Worker, of which the following is a specification.

The object of the present invention is to provide a combined churn and butter-Worker of the kind in which the butter-working device is located inside the clmrning-drum dur ing the churning as well as during the working of the butter. During the churning, the

- butter-working device simply follows the rotation of the drum without the butter-working rollers moving in relation to one another, while during the working of the butter the said device as a whole remains stationary inside the drum which is now slowly rotating while simultaneously the butter working rollers are caused to rotate. In all machines of this kind hitherto known the abovementioned relative movements of the various parts have only been obtained through a rather complicated system of coupling and gearing which increases the cost of the machine and renders diflicult the cleaning of same.

This invention aims at considerably reducing the said gearing and coupling arrangement, which is attained by the means described below and illustrated by the accompanying drawings.

Figures 1 & 2 show two longitudinal sec tions of the machine at right angles to one another. Fig. 3 shows the machine as seen from behind, Fig. 4 shows a perpendicular longitudinal section through a modified form of the machine.

In Figs. 1 to 3, '1 is the mainshaft, going right through the machine and carrying on its front end 2 a handwheel 3. The shaft 1 is fitted into a hollow gudgeon 4 so as to be either by means of a fast and loose pulley 7, 9 on the gudgeon 4, in Fig. 2, or by means of a loose pulley 9, Fig. 1, which with a fork 10 can be brought to gear with a friction-fiange 8 which is in firm connection with the gudgeon 4. Opposite the friction-disk 6 is another, corresponding friction-disk 11 fixed to another hollow gudgeon 12 running in the second bearing 13 of the frame. When the coupling-device 6, 11 is disconnected the shaft 1 may be turned and moved longitudinally in the part 11, 12 which is, by means of a flange 14 fixed to the front plate 16 of the churning-drum 15. Inside the churningdrum the shaft 1 is carried through the front and rear pieces of the butter-working device in such a way as to be capable of turning as well as moving in a longitudinal direction in relation to the latter. of the butter-working device consists of a block 17 with arms 18. The rear piece is a round plate 19. The two pieces 17 and 19 are connected by bolts 20 and provided with fillets 21 to keep the butter away from the ends of the rollers during the working. The one roller 22 is fitted onto the shaft 1 itself in such a manner as to be capable of rotating independently. The other roller 23 is fitted onto a shaft 24 which has its front bearing in the block 17 and projects with the other end through the plate 19. At the back of the plate 19 the shafts 1 and 24 carry the pinions 25 and 26, and have their bearings in a block 27. The plate 19 is fitted tightly, yet easily removably into a collar28 fixed onto the endplate 29 of the drum 15. The collar 28 is connected to a ring or rim 30 provided with teeth on its inner circle 31, the outer circle running on a number of rollers 32 fitted to the rear part of the frame 33. The parts 30 and 32 form the rear support ofthe drum. The part 33 of the frame is annular and its inside diameter is large enough for easily removing and replacing the plate 19 through the opening. On the part 33 is arranged a hinge 34 on which an arm 35 can move, which arm carries a coupling or intermediate pinion 36 and has a recess 37 fitting over the block 27. The intermediate pinion 36, when in the position shown in Fig. 2, will bring a pinion 38, connected to the pinion 25 of the main shaft 1, into gear with the spur- The said front piece wheel 31 the recess 37 at the same time clutching the block 27. 39 is a clamp by means of which the arm 35 may be secured in the position shown in Fig. 2. 40 are the ordinary carriers inside the drum 15.

The working of the apparatus is as follows: For churning, the parts are brought into the position shown in Fig. 1. The arm 35 is swung open. By means of the hand-wheel 2 the shaft 1 is screwed so far to the left that the block 27, or the doublepinion 25, 38 by their pressure against the plate 19 force its rim hard and tightly into the collar 28. This pressure is communicated through the drum to the front plate 16 and the disk 14, so that the parts 11 and 6 are coupled together. When the driving-belt is shifted on to the fixed pulley 7, Fig. 2, or when the loose pulley 9, Fig. l, is engaged with the friction-flange 8, the shaft 1 and the drum as well as the butter-working device connected to the drum by the plate 19 and the bolts 20 etc. will be set in rotation at the same angular velocity as the pulley 7 or 9. In this case none of the cog-wheels is acting. WVhen butter is to be worked, the hand-wheel 2 is released until the edge of the plate 19 runs free of the collar 28 and the friction-disks 6 and 11 are disconnected from one another. The arm is brought into the position shown in Fig. 2, clutching the block 27 so that the butterworking device cannot be rotated as a whole, while the intermediate pinion 36 engages both the pinion 38 and the spur-wheel 30, 31. Consequently when the pulley 7, Fig. 2, or 9, Fig. 1 is revolving at the same speed as before, the rollers 22 and 23 will revolve on their shafts at the same angular velocity as the pulley 7 or 9 while the drum itself will re- .volve at a lower rate of speed, depending on the relation between the number of teeth of the pinion 38 and the spur-wheel 30, 31. The spur-wheel and the three pinions will thus be acting, and the motion will be transferred from the butter-working device to the drum. It is evident that the rollers make the same number of revolutions as that of the drum during the churning, seeing that they have both directly the same rate of revolution as the main shaft itself. For the purpose of collecting the worked butter on to the rollers, if this final operation be desired, the arm 35 is pulled out so far that the pinion 36 is disengaged from the pinion 38, yet not so far that the block 27 is quite released. The driving belt is slipped off, so that the gearing is at rest, and the drum is now turned by hand. The carriers will then gradually deposit the butter on top of the rollers, which are now at rest.

hen the handwheel' 2 is unscrewed and the arm 35 swung out, as shown in Fig. 1, the Whole butter-working device as well as the main shaft 1 may be easily pulled out, en-

tirely or partly, through the rear end of the drum, for cleaning purposes. v

The modified form of construction shown in Fig. 4 only differs from the one shown in Figs. 1 to 3 in so far that the gearing consisting of the spur-wheel 31 on the endplate 29, the pinion 36 on the arm. 35 and the pinion 38 on the central roller pinion 25, is here applied to the front of the machine instead of to the hind part. The arrangement is as follows: A special shaft 41 carries two spurwheels 42 and 43', whose action corresponds to that of the intermediate pinion 36. The hollow gudgeon 12 carries a gear-wheel 44 (corresponding to the spur-wheel 31), and the main shaft 1 carries a pinion 45 (corresponding to the central pinion 38). The shaft 41 is fitted eccentrically into a bush 46 which may be turned by means of an arm 47. On turning this or 180 degrees away from the position shown in Fig. 4, the shaft 41, together with the spur-wheel 42 and 43, will be lowered that much that the latter get out of gear with the pinion 45 and the spurwheel 44 respectively. This is the position of the parts when churning. In Fig. 4 the machine is supposed to be worked by hand by means of a crank 48. But of course mechanical power may as well be used in the same manner as shown in Figs. 1 to 3. With the coupling gear in the position shown in Fig. 4 the machine is ready for butter-work ing, the rotation of the shaft 1 being through the pinion 45 and the spur-wheels 42 and 43 transferred to the spur-wheel 44 and through that to the churning-drum at the diminished rate of speed determined by the number of teeth of the various wheels. Otherwise the machine shown in Fig. 4, is, as regards its arrangement and manner of action, exactly corresponding to the machine shown in Figs. 1 to 3.

Having now particiilarly described and ascertained the nature of the said invention and in what manner the same is to be performed, we declare that what we claim is:

1. I11 a combined churn and butter-worker, the combination of a driving-shaft, a drum through which said shaft extends and which is loosely supported at both ends on said shaft, a butter-working roller mounted directly on said shaft within the drum, a second butter-working roller supported indirectly from said shaft at the side of the firstnamed roller, means for locking said drum to the shaft, and means connecting said rollers with said shaft whereby they may be rotated on their axes from said shaft.

2. In a combined churn and butter-worker, the combination of a drum, a driving-shaft which extends completely through said drum and upon which the same is loosely mounted. at each end, means for locking said drum to said shaft, a butter-working roller mounted TIO directly on said shaft, a second roller, means for supporting said second roller from said shaft at the side of the first roller, and means connecting said rollers and which may connect the same with said drum whereby the movement of the shaft causes the rollers to be rotated on their axes and the drum to be rotated at reduced speed.

In testimony, that we claim the foregoing as our invention, we have signed our names r0 in presence of two subscribing witnesses. OLE CHRISTENSEV. CHRISTIAN PETER SOLBEOK. Witnesses:
